it looks like hes just paywall blocking an updated version on patreon
the patreon version uses th same model as the itch one. just the GUI features are different
i know its the same model lol. he literally updated this post to include his patreon. paywall blocking for basic GUI features is disgusting and malicious, especially when he has 500 supporters.
I don't know if it's "malicious". He's done work, he wants to get compensated.
